Letters Patent No. 65,574, dated June 1l, 1867.

IMPROVED GAB-SPRING.

TO ALL WHOM IT MAY CONGERN:

Be it known that I, EDWIN J. HORNER, of Wilmington, in the county of NewCastle, and in the State of Delaware, have invented certain new anduseful Improvements in Railroad-Car Springs; and do hereby declarethatthe following is a full, clear, and exact description thereof,reference' being had to the accompanying drawings, and to the letters ofreference marked thereon, making a part of this specification.

Figure 1 represents alongitueinal vertical section of the car-spring andbox.

Figure 2, a cross-section.

Figure 3, a plan view of one of the plates.-

My invention has for its object the formation of a cheap, elastic, anddurable spring for the cars.

A represents a metallic case mede oblong or of other suitable form.Within this boxis placed ascries of semi-elliptical shaped metal plates,C. These plates are made of springsteel, and of a length and width tosuit the size box they are to be placedin. The ends of said plates arebent straight a short distance, z 2, so that when two are placedtogether, forming an elongated ellipsis, the flattened ends t neatlytogether. a: represents a semieircular notch made on one edge of eachplate near the centre for the purpose of iitting around arrib, d, whichis made with the box A, as seen in iig. 2. These plates are notconnected together in any manner, and are placed inl the box with oneplate at the bottom with-bulge upwards; then with the plates formingelliptics upon it, and then another plate with bulge downwards iipon theuppermost elliptic, as shown in fig. 1. After the several Iplates areplaced in this manner, a block, B, is set upon the uppermost plate, andthe whole forming a perfect spring. It will be observed that there is agroove, y, in the side of the metal block B, so that it, as well as thesprings, are keptin their places by the rib d, and can easily beextracted for repair in case of one or more of the plates becomingbroken.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

A series of oblong metallic semi-elliptical plates, 'each having anopening, x, near its centre, arranged together as herein shown, 'withfull elongated ellipses between semi-elongated ellipses, placed within abox, A, having a vert-ical rib, d, whereby they are alone secured intheir proper places and heid by the pressure of a grooved` block, B, inthe manncr'as hereinspeciiied.

In testimonythat I claim the foregoing I have hereunto set my hand andseal this 23d day of November, 1866.
